Post-merge fixes: Remove the MYSQL_VERSION_ID checks, because they only
apply to the InnoDB Plugin. Fix potential race condition accessing
trx->op_info and trx->detailed_error.

message:
Make the InnoDB FOREIGN KEY parser understand multi-statements. (Bug #48024)
Also make InnoDB thinks that /*/ only starts a comment. (Bug #53644).
This fixes the bugs in the InnoDB Plugin.
ha_innodb.h: Use trx_query_string() instead of trx_query() when
available (MySQL 5.1.42 or later).
innobase_get_stmt(): New function, to retrieve the currently running
SQL statement.
struct trx_struct: Remove mysql_query_str. Use innobase_get_stmt() instead.
dict_strip_comments(): Add and observe the parameter sql_length. Treat
/*/ as the start of a comment.
dict_create_foreign_constraints(), row_table_add_foreign_constraints():
Add the parameter sql_length.
This is a followup to the fix of
Bug#51920 Innodb connections in row lock wait ignore KILL until lock wait
timeout
in that fix (rb://279) the behavior was changed to honor when a trx is
interrupted during lock wait, but the returned error code was still
"lock wait timeout" when it should be "interrupted".
This change fixes the non-deterministically failing test binlog.binlog_killed,
that failed like this:
binlog.binlog_killed 'stmt' [ fail ]
Test ended at 2010-05-12 11:39:08
CURRENT_TEST: binlog.binlog_killed
mysqltest: At line 208: query 'reap' failed with wrong errno 1205: 'Lock wait timeout exceeded; try restarting transaction', instead of 0...

Support returning 512 and 511 pages for the buffer pool size, this
is undeterministic and probably depends on alignment issues.
The default buffer pool size is 8M (512) pages, which is set in
include/default_mysqld.cnf. So the previous "replace_result 8192 8191"
had no effect.
in the code but they have nothing to do with the kernel mutex split code.
Some subsequent commits use the new functions. This patch has been tested
with: ./mtr --suite=innodb with UNIV_DEBUG and UNIV_SYNC_DEBUG enabled.
All tests were successful.

Merge a patch from Facebook to fix Bug #53290
commit e759bc64eb5c5eed4f75677ad67246797d486460
Author: Ryan Mack
Date: 3 days ago
Bugfix for 53290, fast unique index creation fails on duplicate null values
Summary:
Bug in the fast index creation code incorrectly considers null
values to be duplicates during block merging. Innodb policy is that
multiple null values are allowed in a unique index. Null duplicates
were correctly ignored while sorting individual blocks and with slow
index creation.
Test Plan:
mtr, including new test, load dbs using deferred index creation

basic tests for all these new parameters it is no longer needed to

message:
row_merge_drop_temp_indexes(): Load the table via the dictionary cache.
Allow multiple indexes to be dropped. (Bug #53256)
The bug happened under the following condition:
- there was a user variable of type REAL, containing NULL value
- there was a table with a NOT_NULL column of any type but REAL, having
default value (or auto increment);
- a row was inserted into the table with the user variable as value.
A warning was emitted here.
The problem was that handling of NULL values of REAL type was not properly
implemented: it didn't expect that REAL NULL value can be assigned to other
data type.
Basically, the problem was that set_field_to_null() was used instead of
set_field_to_null_with_conversions().
The fix is to use the right function, or more generally, to allow conversion of
REAL NULL values to other data types.
Problem:
item->name was NULL for Item_user_var_as_out_param
which made strcmp(something, item->name) crash in the LOAD XML code.
Fix:
- item_func.h: Adding set_name() in constuctor for Item_user_var_as_out_param
- sql_load.cc: Changing the condition in write_execute_load_query_log_event() which
distiguished between Item_user_var_as_out_param and Item_field
from
if (item->name == NULL)
to
if (item->type() == Item::FIELD_ITEM)
- loadxml.result, loadxml.test: adding tests
Problem: after introduction of "WL#2649 Number-to-string conversions"
This query:
SET NAMES cp850; -- Or any other non-latin1 ASCII-based character set
SELECT * FROM t1
WHERE datetime_column='2010-01-01 00:00:00'
started to add extra character set conversion:
SELECT * FROM t1
WHERE CONVERT(datetime_column USING cp850)='2010-01-01 00:00:00';
so index on DATETIME column was not used anymore.
Fix:
avoid convertion of NUMERIC/DATETIME items
(i.e. those with derivation DERIVATION_NUMERIC).

Remove UNIV_BTR_AVOID_COPY. It was broken because btr_attach_half_pages()
would get the block, new_block in the wrong order.
Fixing that would have complicated the function even further
for this marginal case.
